Electron Gun Diagnostics Development
Abstract
Two vacuum-diode facilities suitable for test and evaluation of thermionic cathodes and photocathodes were constructed. One facility has been operated at pulsed voltages of + or - 80 kV for 3.3 micro sec with a 1-in- diameter electron beam. The second facility is capable of operating with 250- nsec pulses at voltages of + or - 500 kV; up to 6 kJ is available from the power source. Diagnostic systems for high-speed current, Voltage, and Current-density measurements of the gap are described. Techniques for successful attainment of ultrahigh vacuum environments are also detailed, including development of a unique high-vacuum, High voltage feedthrough.
